php如何调用webservice,
<?php
//require_once('../lib/nusoap.php');
//$client = new soapclient('http://localhost:8080/IBEIntf/services/IBEService?wsdl','wsdl');


/******************************************************************************/
/* 文件名 : soapclient.php
/* 说 明 : WebService接口客户端例程
/******************************************************************************/
include('../lib/nusoap.php');

// 创建一个soapclient对象，参数是server的WSDL 
$client = new soapclient('http://localhost:8080/IBEIntf/services/IBEService?wsdl', 'wsdl');

// 参数转为数组形式传递
$aryPara = array('strUsername'=>'username', 'strPassword'=>MD5('password'));

// 调用远程函数
$aryResult = $client->call('login',$aryPara);

//echo $client->debug_str;
/*
if (!$err=$client->getError()) {
  print_r($aryResult); 
} else { 
  print "ERROR: $err"; 
}
*/

$document=$client->document;
echo <<<SoapDocument
<?xml version="1.0" encoding="GB2312"?>
 <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:si="http://soapinterop.org/xsd">
  <SOAP-ENV:Body>
  $document
  </SOAP-ENV:Body>
 </SOAP-ENV:Envelope>
SoapDocument;


?>

------解决方案--------------------
在浏览器地址栏输入 http://localhost:8080/IBEIntf/services/IBEService?wsdl
